XZ = 40
YZ = 32
By Pythagorean Theorem,
XY = 24
sin Z = opposite / hypotenuse
sin Z = XY / XZ
sin Z = 24/40
In lowest term,
Sin Z = 3/5 (Answer)
To answer his question you will consider that you have 4 whole pieces. If the remaining part is 2/5 (1 - 3/5 = 2/5), that you will need to figure out how many groups of 2/5 it takes to make 4. You get this answer by dividing 4 by 2/5. The answer is 10. You started with 10 pieces.
Answer:
9 marshmallows and 6 graham crackers
Step-by-step explanation:
12:4, 8:4
12/3, 8/2, so divide by three and divide by 2, so 3*2 and 3*3 gives us 9 marshmallows and 6 graham crackers
Answer:
the smaller angle=39°
the larger angle=51°
Step-by-step explanation:
the two angles we are looking for will add up to 90° since they are complementary angles
the smaller angle is rep by 2x
the larger angle is rep by 2x+12
then u equate to 90° since they r complementary angles
2x+2x+12=90°
4x=78x=19.5
x=19.5
2(19.5)=39°
2(19.5)+12=51°
